DC’s Legends of Tomorrow, or simply Legends of Tomorrow, is an American superhero television series developed by Greg Berlanti, Marc Guggenheim, Andrew Kreisberg, and Phil Klemmer, who are also executive producers along with Sarah Schechter and Chris Fedak; Klemmer and Fedak serve as showrunners. The series, based on the characters of DC Comics, airs on The CW and is a spin-off featuring characters introduced in Arrow and The Flash along with new characters, set in the Arrowverse, the same fictional universe. The series premiered in January 2016. Legends of Tomorrow has been renewed for a fourth season which is set to premiere on October 22, 2018.
Time Master Rip Hunter goes rogue after Vandal Savage murders Hunter’s family. Intending to stop Savage, Hunter recruits a team consisting of Ray Palmer / Atom, Sara Lance / White Canary, Martin Stein and Jefferson “Jax” Jackson, who combine to form the hero Firestorm, Kendra Saunders / Hawkgirl, Carter Hall / Hawkman, Leonard Snart / Captain Cold, and Mick Rory / Heat Wave. They discover that the Time Masters are backing Savage in his domination of the world in 2166 to facilitate a successful repulsion of a Thanagarian invasion. Due to Snart’s sacrifice, the Time Masters are destroyed.
In season two, with the Time Masters defeated, the team guard the timeline themselves, and cope with Rip’s absence after he disappears. However, they are plagued by the Legion of Doom, a time-travelling team led by Reverse Flash (Eobard Thawne), who has recruited versions of Damien Darhk, Malcolm Merlyn, and Leonard Snart to find the Biblical Spear of Destiny, with which they can alter their fates. The team is joined by Amaya Jiwe / Vixen, an African superhero from the Justice Society of America, and Nate Heywood / Steel, a modern-day historian who acquires the power to become solid metal and revert to normal skin.
In season three, the team discover that they created anachronisms throughout time, and Rip has formed the Time Bureau to help fix them. Rip tells the team of the demon Mallus, whose follower Nora Darhk has resurrected her father Damien and Amaya’s granddaughter Kuasa, also recruiting Gorilla Grodd so that they can release Mallus from his prison by perverting history. The team loses both members of Firestorm, but is joined by Zari Tomaz, a hacktivist from 2042 whose air-controlling amulet is connected to Amaya’s totem, and Wally West / Kid Flash, a speedster formerly under the tutelage of the Flash.
